Samsung Galaxy A52/A72 are devices released on atoll (SM7125) platform in 2021. Add initial device tree for SM7125 Samsung platform with support for: - Framebuffer - GPIO keys - Hall sensor - Vibrator - Regulators - Reset input - Real-time clock - SD card - Grip sensor - UFS - USB
Tested-by: Stefan Hansson <[email protected]> Signed-off-by: Erikas Bitovtas <[email protected]> --- Samsung Galaxy A52/A72 are smartphones released in 2021 on SM7125 (atoll) platform. This patch series introduces support for SM7125 Samsung devices with the following components enabled: - Framebuffer - GPIO keys - Hall sensor - Vibrator - Regulators - Reset input - Real-time clock - SD card - UFS - USB Along with that, SM7125 was affected by a hang when launching SHM bridge. A similar issue was reported on a similar chipset: https://lore.kernel.org/all/[email protected]/ Add SM7125 to the qcom_tzmem_blacklist to avoid hangs when booting. --- Changes in v4: - Dropped patches which were already merged. - Added the Semtech SX9360 grip sensor. Unlike the rest of sensors which are behind SLPI, this is sensor is bit-banged over 51 (SDA) and 52 (SCL) GPIOs. - Because of a new sensor added to device tree which may require additional review, dropped the Reviewed-By: tags added by David and Konrad. - Link to v3: https://patch.msgid.link/[email protected] Changes in v3: - Updated copyright information. - Added tags given in v2. - Link to v2: https://patch.msgid.link/[email protected] Changes in v2: - Renamed regulator nodes to satisfy dtbs_check. - Renamed pin configurations for SD card to satisfy dtbs_check. - Moved rmtfs_mem to the common dtsi, shifted addresses 0x1000 to the left and added "qcom,use-guard-pages". - Converted decimal 0 to hex 0x0 where applicable. - Pinctrl names are now listed after pinctrl themselves. - Renamed vol-up to button-vol-up to satisfy dtbs_check. - Framebuffer uses cont_splash_mem instead of retyping reg. - Removed pinctrl-names from vibrator. - Added a blank line at the top to the comment for &pm6150_pon - Added a comment explaining what the reserved gpio ranges are. - Added a blank line before "status = "okay"" where applicable. - Link to v1: https://patch.msgid.link/[email protected] To: Bjorn Andersson <[email protected]> To: Konrad Dybcio <[email protected]> To: Rob Herring <[email protected]> To: Krzysztof Kozlowski <[email protected]> To: Conor Dooley <[email protected]> To: Bartosz Golaszewski <[email protected]> To: Kees Cook <[email protected]> To: Tony Luck <[email protected]> To: "Guilherme G.
